Authorization system with a card and a reader

Abstract

An authorization system (10) includes a reader (1) for a reader-card interaction (92) with a card (2), and a logic module configured to assign the reader (1) and the card (2) to each other and to make operable the reader-card interaction (92) based on authorization data comprising reader data and card data. The logic module is further configured to read via a non-contact interface (12.1) device data from an authorization storage device (5) and to assign the reader (1) to the card (2) based on the device data for making operable the reader-card interaction (92). The authorization storage device (5) is arranged spaced apart from the non-contact interface (12.1) at an essentially fixed distance (9), for example during the reader-device interaction (95). Using the device data makes it possible to enable efficiently the reader-card interaction (92) in case the reader data does not match the card data, for example.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a 35 U.S.C. §371 National Phase conversion of PCT / EP2009 / 005954, filed Aug. 17, 2009, which claims benefit of European Application No. 08162479.3, filed Aug. 15, 2008, the disclosure of which is incorporated herein by reference. The PCT International Application was published in the English language.BACKGROUND[0002]1. Field of the Disclosure[0003]The present invention relates to an authorization system comprising a card and a reader) for a reader-card interaction, a method of assigning to each other the reader and the card for making operable the reader-card interaction, and a computer program product for use in the authorization system.[0004]2. Related Art[0005]From the applicant of this application known is an authorization system comprising at least one non-contact tag and a tag reader with a reader logic, e.g. a security module. The tag reader interacts wirelessly with the tags as soon as the tags are placed...

AI Technical Summary

Benefits of technology

This solution enhances system configuration, security, and compatibility by allowing software updates and additions, enabling seamless integration with different authorization systems and applications without hardware changes, thus improving flexibility and cost-effectiveness.

Problems solved by technology

One drawback is the limited interaction rate (speed) because of the contact interface.

Such a change of hardware of the tag reader is cumbersome and may be difficult to realize.

Furthermore, because of the trusted functionality of the reader secret, such changes may not be wanted at all.

That is why the tag reader is often designed in a way that does not allow easy access or replacement of the hardware or hardware parts in which the reader secret is stored.

Due to these drawbacks, the tag readers of a standard system cannot be easily modified or updated to interact with tags of another standard system.

The physical separation is basically unchangeable due to the defined position of the ASD with respect to the reader or the non-contact interface, respectively.

When data, e.g. device data, is stored in the authorization storage device, it becomes more difficult to hack, to attack, to defeat or to circumvent the system, in particular the reader data.
